1. A client expresses difficulty voiding in public places. How should the nurse respond?
- A. Offer to turn on the faucet in the bathroom to help stimulate urination.
- B. Suggest a prescription for a diuretic to increase urine output.
- C. Propose moving to a room with a private bathroom to enhance comfort.
- D. Close the curtain to provide maximum privacy.
Correct answer: D
Rationale: The nurse should prioritize the client's privacy when addressing issues related to voiding discomfort in public places. Closing the curtain in the current room would offer immediate privacy and support the client's needs. Turning on the faucet is not an evidence-based intervention for voiding difficulties. Prescribing a diuretic is not appropriate without further assessment. While moving to a room with a private bathroom might be ideal, it may not be immediately feasible, making ensuring privacy in the current setting the most appropriate action.
2. After a lumbar puncture, into which position does the nurse assist the client?
- A. Flat
- B. Semi-Fowler
- C. Side-lying with the head of the bed elevated
- D. Sitting up in a recliner with the feet elevated
Correct answer: A
Rationale: After a lumbar puncture, the client should be positioned flat. This position helps prevent post-procedure spinal headaches and cerebrospinal fluid leakage. Keeping the client flat for up to 12 hours is crucial in minimizing these risks. Choices B, C, and D are incorrect because elevating the head of the bed or sitting up can increase the risk of complications by altering the pressure in the spinal canal, potentially leading to headaches and fluid leakage.
3. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?
- A. Cardiac output.
- B. Right atrial blood flow.
- C. Left end-diastolic pressure.
- D. Cardiac index.
Correct answer: C
Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.
4. A client who was involved in a motor vehicle collision is admitted with a fractured left femur that is immobilized using a fracture traction splint in preparation for an open reduction internal fixation (ORIF). The nurse determines that the client's distal pulses are diminished in the left foot. Which intervention should the nurse implement?
- A. Verify pedal pulses using a Doppler pulse device
- B. Evaluate the application of the splint to the left leg
- C. Offer ice chips and clear oral liquids
- D. Monitor the left leg for pain, pallor, paresthesia, paralysis, pressure
Correct answer: B
Rationale: Evaluating the application of the splint is the priority as it ensures it is not too tight, which could impair circulation and exacerbate the diminished pulses. Verifying pedal pulses with a Doppler pulse device may be indicated but does not directly address the immediate concern of proper splint application. Offering ice chips and clear oral liquids would not address the issue of diminished distal pulses. Monitoring the left leg for pain, pallor, paresthesia, paralysis, and pressure is important but would not directly address the cause of the diminished pulses in this scenario.
5. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?
- A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
- B. A serum drug level greater than the MEC broadens the spectrum of the drug.
- C. A serum drug level greater than the MEC helps eradicate bacterial infections.
- D. A serum drug level greater than the MEC increases the therapeutic index.
Correct answer: C
Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.
